US-based Terrestrial Energy Proposes Phased Construction Model to Accelerate Deployment of 390 MW Integrated Molten Salt Reactor
Fourth-generation advanced nuclear developer Terrestrial Energy has recently formally submitted to the U.S. Nuclear Regulatory Commission (NRC) a topical report for the Thermal and Electric Facility (TEF) of its Integrated Molten Salt Reactor (IMSR) project. The document proposes a dual-track regulatory review model aimed at allowing key non-nuclear power components of the plant to proceed with construction and enter commercial operation before a full nuclear facility license is obtained. If this regulatory approach is approved by federal regulators, it will effectively break through the economic and approval obstacles that have long constrained the development of the nuclear power industry. In traditional nuclear power projects, because regulatory...
